Looks really good for a first time build, like very impressive. I am guessing you spent a fair amount of time researching and getting all the clamps and jigs set up/built. They are a lot of work, but if you are passionate about it, it really isn't work.

I looked on the internet to understand how others built their hollow wooden surfboards. There are many photos available, so I figured how to build it.
In terms of the plan, I did it myself. As I work as an industrial designer in another area, I know the CAD software. I determined the dimensions and the shape depending on what I had ride before and images of other products available on the market.
Do you have any fin setup suggestion?
I can not wait to try it... But I must first complete the fabrication.

I would advise that you figure out the fin placement and pt in some blocking were the fin boxes will be. That way the install goes much easier, maybe use a closed cell foam to keep it light and easy to work with while helping to keep eater out of the inside of the board.

Wow! That is some nice work you have done there! Can't wait to see the final product. I agree with Trevor on the fin boxes, you might need some reinforcement due to the force that is put on them when riding.

A surfboard traction pad on the tail and for the front foot, I've put some clear grip traction pad from NSI... You can see the graphic thru it, but I'm not convinced of the efficiency of it. Next one, I'll do it otherwise.
The look is great (I think), the construction technic works well. But I've put too much rocker on it (kind of a continuous rocker with no flat area) so it is too slow, even with a single small fin.
I'll correct that aspect on the next one. But I can say that I've learned a lot on this one. Follow my work on RBD Boards Facebook page if you like.
